Tesla Model 3 and Model Y: Why a 12V Lithium Battery Is Worth the Extra Cost

Your Tesla Model 3 or Model Y might be one of the most technologically advanced vehicles on the road, but it still relies on a traditional 12V battery for essential functions like powering the infotainment system, locks, and windows. And while Tesla's stock lead-acid battery does the job, a 12V lithium battery upgrade offers several advantages.

Here's why a lithium battery might be worth the investment:

1. Longevity You Can Count On

A high-quality 12V lithium battery can last several times longer than a conventional 12V lead acid battery. This translates to fewer replacements and significant cost savings down the line. You'll spend less time and money worrying about battery issues and more time enjoying your Tesla.

2. Lighter on Weight, Lighter on Your Mind

Compared to lead-acid batteries, lithium batteries are significantly lighter. Our 12V lithium battery from Ohmmu, for example, weighs less than 9 pounds, making it significantly lighter than the Model 3's OEM 12V lead-acid battery, which weighs 29 pounds. This weight reduction, while seemingly small, can contribute to slightly improved energy efficiency for your Tesla.

3. Eco-Conscious Choice

Lead-acid batteries one of the most toxic products on the planet and the recycling and manufacturing of these batteries are a serious global concern. Lithium batteries, on the other hand, are less toxic. Our 12V lithium battery from Ohmmu features Lithium Iron Phosphate (LiFePO4) chemistry, so it's more friendly to the environment. 

4. Reduced Phantom Drain

Lithium batteries have a lower self-discharge rate than conventional lead acid batteries, so phantom drain on your Tesla would likely be reduced. Reviews from owners have mentioned these benefits, with some stating that they saw dramatic reductions in phantom drain after they switched to using 12V lithium batteries on their Teslas. 

Investing in a 12V lithium battery for your Tesla Model 3 or Y might seem like an extra expense, but the benefits do add up. From extended lifespan and weight reduction to reduced environmental impact and improved efficiency, a lithium battery can actually enhance your ownership experience -- and that's something that's truly worth the extra cost.
